Hi there, I got a query on a toy through my website that has me a bit stumped and I was wondering if anyone here can help.

Here is the message:

"they were Dinosuars that came in tall plastic clear cases(I think it had
kind of lumpy like tree bark or like a volcano type texture to it)
Anyways they had diapers and there was a pink t-rex and a
yellow/orange/red pterodactyl a blue brontosaurus a green stegosaurus and i think a triceratops. Please please please help me. I tried finding them but had no luck maybe you know what they are. I think they might have been called dinokins but I checked and no such luck. "

Additional information: They were around 12" tall (so a considerable size), and were out sometime between the late 80's and 1993 at the very latest.
